Obiettivo

SURVEY OF TRENDS INDUCED BY ACIDIFICATION AND N-POLLUTION IN TREATENEDNW-EUROPEAN NATURE TYPES AND OUTLINES OF PRACTICAL MEASURES FOR CONSERVATION.

DURING THE LAST DECADE A CONSIDERABLE ATTENTIONHAS BEEN GIVEN TO THE PROBLEMS OF SECURING THE FEW REMAINING NATURAL AND SEMINATURAL NW-EUROPEAN NATURE TYPES, I.E. COASTAL AND INLAND WETLANDS AND HEATS. SUCH NATURE TYPES ARE NOW TO A VARYING DEGREE PROTECTED BY LAW AGAINST MAN-MADE ALTERATIONS AND A STEADLY INCREASING AMOUNT OF WORK IS BEING DONE BY STATES AND COUNTRIES AT REESTABLISHING AND MAINTENANCE. - HOWEVER, THIS WORK WAS BASED ON THE ASSUMPTION, THAT THESE NATURE TYPES, GIVEN MECHANICAL TREATMENT IN SUBSTITUTE FOR FORMER EXTENSIVE FARMING, WOULD BE SAFEGUARDEDFOR THE FUTURE. NOW MANY AREAS SHOW SIGNS OF GENERAL CHEMICALLY BASED ALTERATIONS IN SPECIES COMPOSITION, WHICH DO NOT STEM FROM LACK OF TREATMENT IN ACCORDANCE WITH FORMER USAGE.
